“…The elastic modulus of CNTs is approximately 1 TPa-the highest among carbon allotropes. Additionally, CNTs exhibit excellent bendability and plasticity due to their hollow and closed topology [40,[42][43][44]. Figure 2 summarizes the main applications of CNTs in pharmaceutical sciences, medicine, biomedicine, and medical engineering [44][45][46].…”

“…In the absence of light, ROS generation is initiated by electron transfer from biological electron donors (e.g., NADH) to O 2 through CNMs (e.g., carboxylated SWCNTs). ROS generated in either case can cause the inhibition or killing of bacteria through protein inactivation, lipid peroxidation, and nucleic acid damage [42,[107][108][109].…”

As a smart implant, magnesium (Mg) is highly biocompatible and non-toxic. In addition, the elastic modulus of Mg relative to other biodegradable metals (iron and zinc) is close to the elastic modulus of natural bone, making Mg an attractive alternative to hard tissues. However, high corrosion rates and low strength under load relative to bone are some challenges for the widespread use of Mg in orthopedics. Composite fabrication has proven to be an excellent way to improve the mechanical performance and corrosion control of Mg. As a result, their composites emerge as an innovative biodegradable material. Carbon nanotubes (CNTs) have superb properties like low density, high tensile strength, high strength-to-volume ratio, high thermal conductivity, and relatively good antibacterial properties. Therefore, using CNTs as reinforcements for the Mg matrix has been proposed as an essential option. However, the lack of understanding of the mechanisms of effectiveness in mechanical, corrosion, antibacterial, and cellular fields through the presence of CNTs as Mg matrix reinforcements is a challenge for their application. This review focuses on recent findings on Mg/CNT composites fabricated for biological applications. The literature mentions effective mechanisms for mechanical, corrosion, antimicrobial, and cellular domains with the presence of CNTs as reinforcements for Mg-based nanobiocomposites.

“…While FSP has been widely explored for the development of composites, previous studies have primarily focused on incorporating materials such as carbon nanotubes (CNTs) into base metals like Mg and Al. These investigations have demonstrated remarkable enhancements in mechanical properties, including enhanced tensile strength and yield strength, attributed to grain refinement compared to the base material [17,18]. Other researchers also examined the microstructure, microhardness, and wear behavior of FSP-processed composites reinforced with multi-walled carbon nanotubes (MWCNTs) in Mg alloy (AZ31) [19].…”

This article examines the effects of combining silica-rich Halloysite Nano Tube (HNT) and Molybdenum di Sulphide (MoS2) as hybrid reinforcements, dispersed at volumes of 2, 4, and 6%, on the surface of AZ31 alloy through the application of the friction stir process (FSP). The prepared composites were analysed to evaluate their microstructure, mechanical properties, wear resistance, and corrosion characteristics. Microstructural observations indicate the occurrence of rapid recrystallization, resulting in reduced grain size and uniform dispersion. The surface composite demonstrates an increasing trend in hardness with the addition of HNT, while hardness decreases with the inclusion of MoS2. The micro tensile test results exhibits that the composite exhibits an increasing trend in strength, while the micrograph of the fractured surface of the micro tensile specimens reveals reduced ductility. The composite displays enhanced wear behaviour with the increasing volume percentages of HNT and MoS2 particles. Solid lubricant nature of the secondary reinforcement and enhanced hardness due to HNT addition and FSP leads to higher wear resistance of the developed hybrid composite. Additionally, the corrosion rate decreases with the addition of HNT, whereas higher concentrations of MoS2 lead to increased corrosion.
